Answer 1

Answer:

In fig. 1

X = 65

Y = 140

Z = 40

In fig. 2

X = 112

Y = 58

Z = 112

Step-by-step explanation:

IN FIG. 1

75 + 40 + X = 180 (LINEAR PAIR)

115 + X = 180

X = 180 - 115

X = 65

OR

40 + Y = 180 ( LINEAR PAIR)

Y = 160

OR

Z = 40 ( VERTICAL OPP. ANGLE)

IN FIG. 2

58 + X = 180

X = 112 ( LINEAR PAIR)

OR

Y = 58 ( VERTICALLY OPP. ANGLE)

Z = 112 (VERTICALLY OPP. ANGLE)
